What ports does the local FOG server use when imaging?

I’m imaging using FOG 1.2.0 on CentOS 7 and our environment needs to be pretty locked down. It is working with SELinux enabled and I’m using IPtables as well. I opened the firewall using IPtables to accept any UDP and TCP on the entire subnet we’re using. Before I had done this, the imaging process was quite slow, now it happens in 8 minutes or so which is fantastic. The problem is, I’m trying to only allow it on certain ports only. I watched with netstat as it was imaging and saw port 2049 on the FOG server, but I wanted to be sure as to which port(s) the FOG server uses when deploying an image. Thanks all and I appreciate any and all feedback!
